@jmphotography ,
I take it your floor isn't level, hence the need to add a washer, is that correct?
If so, I would look at something at Herbie's, as it should be in your budget.

Actually, I would call them to get the best information on what you should get.
Though I will second Townshend Audio products, they are very effective, but very expensive. I use them on my components to great effect.
